Research reports the accurate performance of the Galaxy Watch 4's body composition measurement sensor

These days, smart watches are equipped with all kinds of different sensors to measure and monitor the health of the body, among the best available, we can refer to the Galaxy Watch 4 series. did A product that has recently been researched regarding the accuracy of its body composition measurement sensor.

If you care about your fitness and health and are looking to stay in shape all the time, you probably use terms such as body mass index. You are familiar with physical or bioelectrical impedance analysis (BIA). But until a year ago, information about these cases could only be obtained through a series of special devices that existed in health clubs and clinics. But these days, we see the aforementioned features in smart watches such as Galaxy Watch 4 and 5. But the important question here is how accurate are these products in measuring the mentioned information? And the Pennington Medical Research Center as well as the Hawaii Cancer Center have conducted a joint study to find out if the Galaxy Watch 4 can accurately measure BMI and BIA.

109 people participated in this test and the information obtained by Galaxy Watch 4 from their BIA was finally obtained with the results accurate medical devices are compared to determine how accurate Samsung Galaxy is in this field. The information obtained from the Galaxy Watch 4 includes fat-free mass, fat mass, bone mass, metabolic rate and body water content, which are very useful information for a professional athlete and can help users gain a correct understanding of their health. .

• Pixel Watch against Galaxy Watch and Apple Watch; Which Watch is the winner?

BIA accuracy obtained by Galaxy Watch 4

Finally, the results obtained from Galaxy Watch 4 showed that between it and the data obtained by There was a 97-98% match for medical devices. In other words, the aforementioned Galaxy Watch has recorded slightly lower data than reality. As a result, you can count on these devices and their abilities when laboratory and medical products are not available.

In order to increase the accuracy of measuring criteria, Samsung has provided a series of solutions, which include:

• Measure at the same time of day.
• Do the tests fasting.
• Do the tests after a bath.
• Do the tests Do it when you are not on your period.
